Entangled Scent of a Charge
M. Asorey, A. P. Balachandran, F. Lizzi +1
We argue that the ground state of a field theory, in the presence of charged particles, becomes an entangled state involving an infinity of soft photons. The quantum field vacuum i…
Equations of Motion as Constraints: Superselection Rules, Ward Identities
M. Asorey, A. P. Balachandran, F. Lizzi +1
The meaning of local observables is poorly understood in gauge theories, not to speak of quantum gravity. As a step towards a better understanding we study asymptotic (infrared) tr…
Isoperiodic classical systems and their quantum counterparts
M. Asorey, J. F. Carinena, G. Marmo +1
One-dimensional isoperiodic classical systems have been first analyzed by Abel. Abel's characterization can be extended for singular potentials and potentials which are not defined…
